How social media in China shapes eating disorders ^{CEFR B1}

Social media in China has reshaped how eating disorders are discussed. On platforms such as Xiaohongshu, people use terms like "ED" and coded labels such as "ED 女" or "CT" (Cui Tu, induced vomiting) to form semi-hidden networks. In these spaces, extreme thinness is often presented as discipline and a source of belonging rather than a medical problem.

Searches show posts that track strict routines. Some users list daily intake with headlines such as "160 cm/33 kg" or "160/29 kg daily intake." Others post daily check-ins with weight and calories, for example "Day 12: 500 kcal, no carbs, stayed strong." Comment sections can praise restriction and encourage more loss.

Research reports that the number of Chinese teenagers with eating disorders has almost doubled in the past three decades. More recent studies find that more than 21 per cent of teenagers showed signs of eating disorders and more than 11 per cent had clinically significant symptoms. The highest risk is among females aged 15 to 19 from lower-income families and poorer regions. Researchers link the rise to pubertal development, greater social media exposure and body image concerns. Experts warn that removing content alone will not solve the problem and call for better support through schools, families and wider society.
